But, evidently we don't need every acre do we? And, even though there is a finite numbers of acres all it takes "enough" to foul up the market. End users (contractors) who have supply under contract can stay out of the market for a very long time. Hence the term "residual supplier". If all your neighbors are under contract with the local ethanol plant, feed mill or whatever and you are not, do you not think they can draw on their contracted supplies and not need yours until they have exhausted their supply? What happens when they never use all their contracted supply, how do you get a decent market for yours?
